With the news that unleaded avgas is starting to be distributed in the US now, we've decided to get started early on perfecting closed loop feedback control software for aviation applications.
We'll be shipping off a modified ECU to one of our test partners in Colorado tomorrow for flight testing later this month. We have several strategies in mind for O2 sensor fault detection and correction, building off our 20+ years experience with this feature in our automotive ECUs.
Initial goals for production ECUs would be to have user programmable AFR targets for several rpm and load ranges. The O2 sensor will command auto fuel trim based on these parameters.
The eventual goal would be something closer to full FADECs where all fueling and timing is automatic. I'm not sure how well that can be implemented on multiple engine types and configurations in the Experimental world but we can explore heading in that direction at least and see how we end up.
We'll also be acquiring a test engine we can bench run under load with a prop later this month to validate code and performance.
The hardware is already in place on present EM-5 ECUs to implement closed loop control so only a reflash would be involved to have this capability.
Always interesting and challenging to work on new projects.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
